Goku

Dark Goku is one of the main antagonist of Shadow and Vegeta Unite!.

Personality
Due to unknown reasons, Goku has become an evil demented being. Dubbed "Dark Goku", he is now a cold and rutheless battler, who takes great delight in mocking his foes. He talks with a certain eloquence, that makes his foes feel like they`re friends. He is good at deceiving his foes, and would strike them without mercy. One such moment is when he made Tails believe that he was weaker, only to power up later.

Goku is also completely loyal to Dr. Robotnik. To please him, Goku has attacked a village, massacred the residents, and set the village a blaze. Goku is also great allies with Sonic. Both have teamed up to defeat their foes without hesitation, although if they are friends or not is not known.

It is interesting to note, that when he saw Goten, he seemed conscern, although this didn`t stay long, as he tried to kill him later.

Abilities
Goku is a cold blooded murderer who hunts his opponents without mercy. His power level has also increased dramatically, to the point, that a normal Kamehameha is as powerful as a Super Kamehameha. He is also incredibly quick, easily dodging Vegeta`s kick, and countering with a punch. Other than that, Goku still retains his fighting style and moves, except they are now greatly increased.

Of all of Goku`s signature moves, only one has been seen so far.
